IMMEDIATE
Fix all the BUGS (see BUGS) of course!
TASKS OUTSTANDING
Documentation.
- Maybe an FAQ to complement Bernhard's HOWTO
all those standard questions about MPEG, VCD, SVCD
all those standard questions about busted audio drivers
Code hygiene basically: GNU guidelines!
Basically if you want a nice example of how it should be done take
a look at the source code for vcdimager!
- A lot of the code is in fairly poor shape layout and stylistically.
Minimally, some needs running through a C prettifier and having
stuff like "unsigned char" replaced with appropriate types from
stdint.h via utils/mjpeg_types.h.
- Need to test and build scripts for in-line multiplexing.
- The filtering / decimation code in the lav* utilities is now redundant
with yuvscale in place... it should be removed once we're happy with
yuvscale.
Major
- Continuation of frozen encoding sessions.
- Try switching to the somewhat faster transposed fDCT from libavcodec.
- "Back-up and try again" and/or "two pass" bit-allocation / quantisation
control on a frame by frame basis.
Maybe sometime
- Find a proper SSE fDCT and iDCT.
- Test support for field pictures to mplex. Not urgent since for most
sources frame pictures with field DCT/motion compensation seems to
give better results.
- Improve the appearance of dark scenes. At the present time dark scenes
are very prone to splotchy or grey blockiness. Locally reduce quantisation
and, if necessary, switch to a different matrix if the dark is long enough.
The dark scenes don't use many bits anyway so its not too greedy..
